Email attachments

XMission rejects email attachments with commonly malicious file formats as a security measure to prevent potential viruses from impacting customers. Rejecting emails with executable files, for example file.exe, will protect you from possibly receiving malicious software containing a virus or malware.

This blocking is applied to all inbound and outbound email. Automatically, a reject notice will be sent to any sender attempting to send to, or from, the XMission mail system.

File types rejected end in: scr, vbs, dll, exe, shs, bat, lnk, pif, chm, hta, com, cmd

XMission customers needing to send a file type on this list can archive it as a ".zip" file first, then send that file as an attachment.
